Hi, I'm a new to squid and ICAP and requesting for help. I'm trying to setup a URL filtering feature provided by c-icap server. I'm having trouble configuring my Squid Server to communicate with the ICAP server setup on a remote machine. If I have ICAP server on same machine as Squid server(127.0.0.1), there is no issue in communication between squid and ICAP server. URL blocking also occurs successfully Following is the setup: I have setup Squid on 192.168.10.8 and ICAP server on 192.168.10.9, on 192.168.10.8 in squid.conf file I have provided "icap_service service_req reqmod_precache routing=on bypass=1 icap://<icap server ip>:1344/url_check_module". When I try to open any URL on the machine where squid is setup I get following error in squid log "optional ICAP service is down after an options fetch failure: icap://192.168.10.9:1344/url_check_module [down,!opt]" (I have setup my iptables to route all the http traffic to squid port 3128) I have attached my squid config file setting below Any help here is much appreciated Thanks Anil ------------------------------ ------------------- # # Recommended minimum configuration: # acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 # Example rule allowing access from your local networks. # Adapt to list your (internal) IP networks from where browsing # should be allowed acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src 172.16.0.0/12 # RFC1918 possible internal network acl localnet src 192.168.0.0/16 # RFC1918 possible internal network acl localnet src fc00::/7 # RFC 4193 local private network range acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl SSL_ports port 443 acl Safe_ports port 1344 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT # # Recommended minimum Access Permission configuration: # # Only allow cachemgr access from localhost http_access allow manager localhost http_access deny manager # Deny requests to certain unsafe ports http_access deny !Safe_ports # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !SSL_ports # We strongly recommend the following be uncommented to protect innocent # web applications running on the proxy server who think the only # one who can access services on "localhost" is a local user #http_access deny to_localhost # # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS # # Example rule allowing access from your local networks. # Adapt localnet in the ACL section to list your (internal) IP networks # from where browsing should be allowed http_access allow localnet http_access allow localhost http_access allow arjun_ip # And finally deny all other access to this proxy http_access deny all # Squid normally listens to port 3128 http_port 3128 intercept # We recommend you to use at least the following line. hierarchy_stoplist cgi-bin ? # Uncomment and adjust the following to add a disk cache directory. #cache_dir ufs /var/spool/squid 100 16 256 # Leave coredumps in the first cache dir coredump_dir /var/spool/squid icap_enable on icap_service service_req reqmod_precache routing=on bypass=1 icap://192.168.10.9:1344/url_check_module adaptation_access service_req allow all icap_service_failure_limit -1 # Add any of your own refresh_pattern entries above these. refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320
